Yesterday ( October 27,2008), Microsoft unveiled details of two new operating systems. Currently, the most commonly used operating systems are Windows XP and Windows Vista. Although frequently criticized, often by those who have never used it, Vista is actually are very stable rich environment in which to work, particularly when used with up to date machines.
Nevertheless Microsoft has decided to press ahead with successors for Vista. In late 2009 Windows 7 will be released. It will be much like Vista. Around the same time Microsoft will release Windows Azur, an operating system that lives on Microsoft servers and not on your computer. This is called "Cloud Computing", the "Cloud" being the internet. Basically this means that you wont need an operating system or programs: they will all live in the "Cloud".
Whether this works out or not remains to be seen. However, many companies are already trying this, both with Microsoft and with Google products.
"Cloud Computing " is one of the most used technology buzz words at present.
